72.6
total all of them
but if you want a quicker way then 16multiplys2 and 13 multiplys 2 then add 7.3 times 2
Step-by-step explanation:
We know that the lenght of an arc is pi. Therefore:
pi = 1/2pi*r where r is the radius
r = 2
On one side we have 2 circles, so the lenght of 1 side is 2. The perimeter will be 2*4 = 8.
*Note: the first equation I wrote can be derived from the general equation for calculating the lenght of a circumference known its radius (L = 2 * pi * r).
